YMvKmb Cable

What is YMvKmb Cable?

The YMvKmb cable is a Dutch-standard, low-voltage (0.6/1kV) flame-retardant unarmoured power cable accredited under KEMA K42C-1-4-D and European standard HD 604-S1-4D. Engineered for fixed installations in dry and humid industrial premises, warehouses, and storage depots exposed to fire and explosion risks, it is suitable for surface conduit runs and under-plaster installations but is strictly not suitable for direct underground laying.

Featuring XLPE insulation rated for continuous +90°C conductor operation, the cable delivers superior dielectric performance and high current-carrying capacity. The cores are surrounded by an extruded PVC filler and sheathed in a heavy-duty grey flame-retardant PVC outer jacket. Tested to EN 60332-3-24 Category C, the jacket effectively inhibits vertical flame propagation along vertical risers and enclosed cable containment systems.

YMvKmb Cable Construction

• Conductor: Plain annealed copper conductor; Class 1 solid copper for sizes up to 10mm², and Class 2 stranded circular copper for sizes 16mm² and above.
• Insulation: Cross-Linked Polyethylene (XLPE) compound providing excellent insulation resistance and thermal endurance up to +90°C.
• Filler: Extruded Polyvinyl Chloride (PVC) compound to maintain a compact, circular cross-section.
• Outer Sheath: Heavy-duty flame-retardant Polyvinyl Chloride (PVC FR).
• Core Identification: Color-coded cores conforming to HD 308-S2 and European low-voltage wiring conventions.
• Sheath Colour: Industrial Grey.

Applications

YMvKmb cables are designed for primary and secondary low-voltage electrical distribution in commercial buildings and hazardous industrial environments requiring enhanced fire safety:

• Industrial Plants & Depots: Chemical manufacturing plants, logistics hubs, and processing factories subject to potential fire or explosion risks.
• Conduit & Under-Plaster Routing: Fixed wiring drawn through protective conduits, surface-mounted on walls, or embedded under plaster.
• Switchboard & Motor Supply: Power distribution to industrial machinery, motor control centers (MCC), sub-distribution panels, and lighting grids.
• Dutch Installation Standard Projects: Electrical wiring conforming to NEN 1010, IEC 60364, DIN VDE 0100, CEI 20-60, and NF C15-100 standards.

Specifications & Dimensions

Huadong Cable Group manufactures the full range of YMvKmb cables across single-core (10mm² to 400mm²), 2-core (1.5mm² to 50mm²), 3-core (1.5mm² to 300mm²), 4-core (1.5mm² to 300mm²), and 5-core (1.5mm² to 95mm²) configurations. Rated for an operating voltage of 0.6/1kV (test voltage 3.5kV) within an operational temperature range of -15°C to +90°C and short-circuit capability up to +250°C, the cable series features nominal overall diameters from 8.1mm (single-core 10mm²) up to 75.2mm (4-core 300mm²) with unit weights spanning 121 kg/km to 14,303 kg/km. Conductor DC resistance at 20°C strictly follows standard limits (12.1 Ω/km for 1.5mm² down to 0.0470 Ω/km for 400mm²), delivering multi-core air-rated current-carrying capacities up to 638A under a minimum bending radius of 12 times the overall diameter per HD 604-S1-4D standards.

Frequently Asked Questions

Q: Can YMvKmb cable be buried directly underground in soil?
A: No, YMvKmb is an unarmoured cable and is explicitly classified as not suitable for underground installation; direct-burial applications require armoured cables such as VO-YMvKasmb or VG-YMvKasmb.

Q: What is the main operational advantage of XLPE insulation over PVC in YMvKmb cables?
A: XLPE withstands continuous conductor temperatures up to +90°C (compared to +70°C for PVC), providing higher current-carrying capacity, superior short-circuit thermal withstand up to +250°C, and lower dielectric loss.

Q: What is the significance of the EN 60332-3-24 Category C fire test?
A: It verifies that bunched cable assemblies resist vertical flame spread under defined test conditions, ensuring the cable will self-extinguish when the fire source is removed.

Q: What payment terms does Huadong Cable accept for international orders?
A: We accept standard international commercial payment terms, primarily Telegraphic Transfer (T/T, 30% advance deposit and 70% against shipping documents) and 100% Irrevocable Letter of Credit (L/C) at sight.
